Private branch exchange is a private telephone network used within an
enterprise. Users of the PBX share a certain number of outside lines
for making telephone calls external to the PBX. Most medium-sized
and larger companies use a PBX because it's much less expensive than
connecting an external telephone line to every telephone in the
organization. In addition, it's easier to call someone within a PBX
because the number you need to dial is typically just 2 or 4 digits.
